GOIN-CONTROLLED APPARATUS.` ff

SPECIFICATION forming part of Letters Patent No. 511,594, dated December 26, 1893.

Application filed May 8. 1893. Serial No. 473,466. (No model.)

To all whom, t may concern:

Be it known that I, CHARLES WILLsoN DE- LANEY, a citizen of the United States,`and a resident of Hammond, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Coin-Controlled Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this speciiication,and in which-f Figure 1 is a perspective view of my iinproved apparatus. Fig. 2V is a sectional View of the same, on a vertical plane intersecting the inflation box at right angles; the dotted lines indicating the motion or play of the flexible diaphragm and its attachments when the apparatus is in operation. Fig. 3 is a plan or top view of the apparatus; and Fig. et is a sectional detail view, showing a somewhat .modified construct-ion and arrangement of the inflation box with its air-tubes.

Likeletters of reference denote corresponding parts in all the figures.

This invention relates to coin-controlled apparatus of that particular class or type in which the machine is operated by blowing into a tube which communicates with a box -having a flexible diaphragm', by the motion of which the operating parts are actuated; the dropping of the coin releasing a dog or pawl which permits the necessary motion of the flexible diaphragm; and it consistsin the novel construction andcombination of parts of the device or apparatus which will be hereinafter more fully described and claimed.

Referring to the drawings, the reference letter A denotes a short post or standard of Wood or metal, secured in a base, B, which is permanently fastened inthe bottom of a suitable box or casing (not shown) by the screws b. The standard A is bored through transversely, as shown at a, for the insertion of the horizontal tube C, which is held in place removably, in its seat or aperture a byineans of a thumb-screw D, which works in a threaded socket, d, in the upper end of the standard,

with its lower end bearing against tube'C, as clearly shown in Fig. 2. To yone end of this horizontal tube C is fastened the inflationbox E, which is preferably of circular shape, with a rigid head F Von one side, and, on the opposite side, a rim orannular flangef, which supports the flexible circular diaphragm F', made, preferably, of a thin sheet of indiarubber. To the middle of this flexible and elastic diaphragm or cover is Asuitably secured a circular' plate or disk G, to the center of which is attached a stem 0r thin rod H, which projects through coinciding apertures, t' and j, in thewguide-plates I and J, which said plates are su pported in parallel arms or brackets, K K, fastened to and projecting outwardly from the rigid rini of the box E. The movements of the disk G and its lstem H are further guided and controlled by a short arm g, which is fastened upon the disk and works through an aperturet" in the innermost guide plate I. The two parallel guide-plates I and J are connected by braces, L L, on opposite sides of the central movable stem H. 'lhat part of said stem H'whichlies between the parallel guide-plates I and J is encircled by a coiled spring M, the outer end of which takes its bearing against plate J, while its other or inner end bears or presses against a pin, h, inserted crosswise through stem H, so'

that the tension'of the coiled spring will operate, normally, or when the machinejis at rest, to maintain the disk G, and with it the flexible diaphragm'. F', in itsv down or at position, as shown in full lines in Fig. 2. the outer en d of the stem H is fastened, approximately at right angles, the coin-receiver N, which Ais in the nature of a shallow box or receptacle, with open top and bottom, and of such size, interiorly, that it Will fit snugly a lcoin (for example, a nickel, a dime, ora one cent piece dropped into it through a chute O, the upper lend of which communicates -with a slot'in the inclosing box or casing within which .the apparatus is placed, but only part ofwhich is shown on the drawings.

Upon the guide-plate J are fastened twoforwardly projecting short parallel armsP P, between which is hung a short rock-shaft Q, in which is fastened a bent arm R, carrying a Weight or counterpoise R at its free end. In the rock-shaft Q is also fastened an arm S, the outer end of which projects into the mid- ICO dle part of the coin-receiver N on its under side, through a narrow vertical slot n, while its opposite or inner end is bent in a downward direction and beveled, as shown at S',

to form a pawl adapted to engage or inter.

lock with a notch, s, cut in the movable stem H. When the pawl, due to the operation. of the weighted arm R, is in its down position, as shown in full line in Fig, 2, so as to engage the notch s, it will be seen that it will prevent the stem Il from moving outwardly from box E; but such movement may take place freely when the pawl is lifted out of and disengaged from its notch s, as shown in dotted lines.

The tube C, to one end of which the ination-box E is attached, and which, therefore, forms a support or bearing for said box and its attachments, also serves as a conduit or support for two flexible tubes, shown at T and T. One of these (T) has a mouth-piece t, which should project, with a suitable length of flexibletubing, outside of the box or casing which incloses the entire apparatus, and forms the blow-pipe or inating-tube by and through which the apparatus is primarily operated (after the dropping of a coin into the receiver N), while the other tube T', which is of smaller dimensions (i. c. thinner) than the blow-tube, formsthe outlet or exhaust for the air blown into the box E through tube T t. These two tubes, T and T', may be located and arranged in various ways; for example, as in Figs. l, 2, and 3, where they both open up into box E through its rigid head F; or, as in Fig. 4, they may be inserted into the iniiation-box through the sides or rim of the same. In any case, the inlet tube T is carried up against the middle part of themovable plate G, on the inside, while the exhaust-tube T is clear and free from contact with the diaphragm. The other end of the exhaust tube may be connected with an automatic vendingmachine, a lung-tester, or any other form of apparatus or contrivance adapted to be operated by a current of air. If desired, the blow-tube T may be provided with an enlargement or bulb, U, adapted to intercept dust, dirt, or any foreign matter which may pass through the month-piece t and tube T, and prevent the same from reaching and finding lodgment in the inflationboxE.

From the foregoing description, taken in connection with the drawings, the operation of this apparatus will readily be understood. When it is desired tooperate the device, a coin of the proper denomination must first be deposited in the coin-receiver N through chute O. y The lower rim of the coin, intercepted by and resting upon that end of the pawl-arm S which projects into the bottom of the coin-re ceiver through the slot or opening n, will by its weight, overbalance the connterpoise R on arm R so as to rock or tilt the shaft Q in its bearings between arms P P, thereby lifting the pawl S out of the notch s in the movable stem Il. By-now blowing through the mouth-piece tand tube T into box E, the ilexible diaphragm F of the latter will be raised or bulged, as shown in dotted lines, thereby pushing upon disk G and its stem H so as to push the coin and coin-receiver at the outer end of the stem away from the end of the retaining arm S, thus permitting the coin deposited in the receiver to drop through the open bottom of the same into a suitable receptacle or drawer placed below. As long as the blowing continues, spring M will remain compressed and the air will pass from theinfiation-box out through the exhaust tube T into the vending apparatus, tester, or whatever other contrivance is connected with the con trolling device. But the moment the blowing stops, spring M will relax and force the diaphragm F' back into its normal fiat position, carrying with it the disk G and stem H, so that the pawl (actuated by the weighted arm R and rock-shaft Q) will again drop back into and interlock with the notch s, thus locking the apparatus and preventing inflation of box E until its stem is again released from the retaining pawl by the dropping ot another coin into the receiver, the bottom of which is now again closed by the end of arm S projecting into the receiver through the slot on one side thereof.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States-- The combination in a coin-controlledapparatus of the described type, of' the inflationbox having a flexible diaphragm provided with a central disk and projecting` notched stem carrying a coin-receiver at its outer end, the in ilation air-tube, the exhaust air-tube, the spring encircling the notched stem, the pawl engaging with one end the notch in the stem and projecting with its other end into the open bottom of the coin-receiver, the guide-` plates, the rock-shaft and the weighted arm; all constructed and combined to operate substantially in the manner and for the purpose shown and slet forth.

In testimony that I claim the foregoing as my own I have hereunto aliixed my signature in presence of two witnesses.
